Running the engine once a month does more harm than good unless the rig is driven for at least 30 minutes.
Sorry can't agree with that.
The engine gets QUITE hot enough from running for 30 minutes to boil off any moisture that accumulates in the crankcase or exhaust......and the transmission is mostly sealed, doesn't accumulate moisture and doesn't need to be heated periodically.
You do have to run it long enough to get the engine parts hot but no need to actually go down the road to do that.
P.S. Just noticed that you are in Canada. If it is REAL cold when it's time for a monthly exercise and inspection.....I might just skip it or slip the schedule a bit. There is no good reason to be starting things up at -20 F just for exercise.
